  1. Isolation of plasmids from abow cultures.
  2. Control digest of isolated plasmids with BamHI and SacI.
  3. Gel electrophoresis - wszystkie wyszły dobrze oprucz ompa_alfa - zakażone czymś.


Conclusions:

  1. Almost none of tested constructs give resistance to ampicillin without prey protein added to culture medium.
  2. Interaction between hunter and prey is not nessesery to makes cells ampicillin resistant(Omp_alpha and Omp_omega growth with prey)
  3. OmpA-alpha may be comtaminated with antibiotic resistance bacteria, alpha do not need interaction of A and Z to bind to omega - maybe we must give bacteria less pray

    4. Cloning of protein A DNA to GeneArt plasmid

    Antoni

    1. Colony PCR on colonies from plates with transformations pGeneart+A.
      Primers used: AP+NotI and AL+SacI.
    2. Gel electrophoresis.
    3. Confirmed transformant colonies inoculated to liquid LB with ampicillin.
    4. Inoculation to liquid LB with ampicillin: pET15b+OmpA-alpha.

    Cloning of alpha to pACYC177+OmpA_A_omega and pACYC177+OmpA_Z_omega

    Michał K.

    1. Isolation of plasmids from cultures inocluated on previous day.
    2. Control digest of isolated plasmids with FastBamHI and FastAcc65I (Fast Digest buffer).
    3. Gel electrophoresis - no proper clones founded.
